Hello Community, please I have a problem with this code, when i run it they said:
Error in NOUVEAU (line 107)
convnet= trainNetwork(trainData,layers,options);
Caused by:
Layer 'add11': Unconnected input. Each layer input must be connected to the output of another layer.
Detected unconnected inputs:
input 'in2'
Layer 'add12': Unconnected input. Each layer input must be connected to the output of another layer.
Detected unconnected inputs:
input 'in2'
Layer 'add21': Unconnected input. Each layer input must be connected to the output of another layer.
Detected unconnected inputs:

Layer 'add22': Unconnected input. Each layer input must be connected to the output of another layer.
